0: Positive logic
The output terminal is valid when being connected with COM, and invalid when being
disconnected from COM.
1: Positive logic
The output terminal is invalid when being connected with COM, and valid when being
disconnected from COM.

0: Direct start
–
If the DC braking time is set to 0, the AC drive starts to run at the startup
frequency.
–
If the DC braking time is not 0, the AC drive performs DC braking first and
then starts to run at the startup frequency. It is applicable to small-inertia load
application where the motor is likely to rotate at startup.

at the tracked frequency. Such smooth start has no impact on the rotating motor. It
is applicable to the restart upon instantaneous power failure of large-inertia load. To
ensure the performance of rotational speed tracking restart, set the motor parameters

–
If the pre-excited time is 0, the AC drive cancels pre-excitation and starts to run at
startup frequency.
–
If the pre-excited time is not 0, the AC drive pre-excites first before startup,
improving the dynamic response of the motor.

To complete the rotational speed tracking process within the shortest time, select the proper
mode in which the AC drive tracks the motor rotational speed.
